SUMP PUMP MOUNTING Filed Jan. 2'7, 1957 2 Sheets-Sheet 2 Patented Nov. 9, 1937 UNITED. STATES PATENT OFFICE.

2 Claims.

The present invention relates to sump pump and has for its principal object to provide a mounting for the pump providing for the quick and easy-removal of the impeller and also em- 5. bodying a rigid'supporting means for the lower endof the pump shaft.

A further object is to provide a novel packing construction for the lower end of the pump shaft.

A still further object is to provide a liquid- 10 tight housing for the drive shaft, pump shaft and gears connecting the same to enable the operation thereof in a bath of oil and to otherwise improve the construction and assembly of the pump mounting.

15 Other-objects and advantages reside in the details of construction and operation .as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer 20 to like parts throughout and in Which:

Figure l is a side elevational view of the pump assembly with parts of the casing broken away and shown in section.

Figure 2 is a similar view of the gear housing 25 with parts broken away and shown in section.

Figure 3 is a bottom plan view of the impeller.

Figure 4 is a sectional view of the lower end of the housing for the pump shaft.

Figure 5 is a fragmentary sectional view of the 30 housing for the drive shaft of the pump.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a cylindrical casing 35 open at its lower end and having a laterally extending discharge pipe 6 adjacent its upper end. An opening I is formed in the top 8 of the casing through which a pump shaft housing 9 is inserted, the upper end of the housing being supported by a plate Iii bolted as at H to the top 8, said plate sealing the opening I in the top of the casing. A pump shaft I2 is positioned in the housing 9, the lower end of the shaft projecting from the lower end of the housing and is provided with a plate l3 secured to the tapered lower end I4 of the shaft by a nut l5. The plate 13 is formed with openings 16 for receiving bolts I! for securing the lower end of the shaft to an 7 impeller designated generally at 18.

50 The impeller I8 is formed of a plate or disk 19 having a central opening 29 for receiving the hub portion 2| of the plate l3 and a series of openings 22 for receiving the bolts l1 whereby to firmly secure the impeller to the shaft. The

55 underside of the plate I9 is formed with a series of arcuate blades 23, said blades being positioned in closely spaced relation with a concaved defiector 24 secured within the bottom portion of thecasing 5 and having a central opening 25 through which fluid is drawn by the impeller up- 5 wardly through the casing for discharge through the pipe 6.

The shaft I2 is provided immediately above the plate I3 with a packing cup 26 within which the lower end of the housing 9 is telescopicalli inserted, as more clearly shown in Figure 4 of the drawings, said cup having a flanged upper edge 2! through which bolts 28 are inserted for attaching to a flange 29 formed on the housing.

A fibrous packing sleeve 30 is positioned in the lower end of the housing 9 and the cup 26 is supplied with a suitable quantity of packing material 3| which it will be apparent is compressed by the tightening of the bolts 28 to draw the cup 26 upwardly.

The flange 29 is seated upon the inwardly extended flange 32 of a ring member 33 supported within the lower end of the casing 5 by a spider 34. The ring member 33 is of a diameter sufficient to permit the withdrawal upwardly of the pump shaft [2 and housing 9 with the plate [3 attached thereto upwardly through the ring member after the impeller has been removed therefrom.

A tubular member 35 extends upwardly .from the plate [0 for supporting a gear housing 36, said housing including upper and lower plates 31 and 38 connected by bolts 39 and between which a ring member 40 is positioned. The shaft [2 extends upwardly through the plate l0 and bottom plate 38 of the housing into the latter, the upper end of the shaft having a ring gear 4| attached thereto by means of a plate 42. A bearing assembly 43 is interposed between the shaft I2 and tubular member 35 to center the shaft with respect thereto.

The ring gear 4| is driven by a pinion 44 on one end of a drive shaft 45 mounted in a tubular housing 46 which has one end attached to the gear housing 40 and provided with a bearing as- 45 sembly 41 for supporting the shaft 45 therein. The opposite end of the shaft 45 projects from the housing 46 and is spllned as at 41' to provide a suitable drive connection for the shaft. Adjacent the end of the housing 46 is a flange 48 having bolts 49 attached thereto for drawing a packing cup 50 inwardly toward the shaft, said packing cup being provided with a suitable quantity of packing material 5| to provide a liquidtight seal between the shaft and the housing.

Bearings 52 are also interposed between the shaft and the housing to center the shaft therein.

A filler neck 53 extends from the gear housing 40 by means of which a suitable quantity of lubricating oil may be supplied to the gear housing and shaft housings 9 and 46.

Brackets 54 are secured to the side walls of the casing 5 by means of which the casing may be anchored to beams or the like to secure the apparatus in an upright position during the pumping action.

The bolts ll may be removed from the plate l0 and the housing 40 turned to any desired po: sition relative to the casing 5 to obtain the most suitable position for connecting the shaft 45 to the source of power.

It is believed the details of construction and operation of the apparatus will be readily understood from the foregoing without further detail explanation thereof.

Having thus described the invention what I claim is:

1. A sump pump mounting comprising a casing open at its lower end and having a discharge port adjacent its upper end, a pump shaft positioned in the casing and extending through the top thereof, a plate secured to the lower end of the shaft, an impeller removably secured to said plate, a housing for the shaft, a flange on the housing and a ring member supported within the casing and forming a support for the flange to center the shaft in the casing, said ring member having a central opening to provide for withdrawal of the shaft and plate therethrough after removal of the impeller from the shaft.

2. A sump pump mounting comprising a casing open at its lower end and having a discharge port adjacent its upper end, a pump shaft positioned in the casing and extending through the top thereof, a plate secured to the lower end of the shaft, an impeller removably secured to said plate, a housing for the shaft, a flange on the housing and a ring member supported within the casing and forming a support for the flange to center the shaft in the casing, said ring member having a central opening to provide for withdrawal of the shaft and plate therethrough after removal of the impeller from the shaft, a packing cup adjacent the lower end of the shaft and means for drawing the cup upwardly about the lower end of the shaft housing.
